I heard about how turbo might decrease the life of your car. I was wondering is there actual proof of this? If anything i think it should increase it :thumbsup:

With a ghetto setup on an N/A motor without proper tunning, the engine's lifespan will probally be reduced. Damaged ringlands come to mind. How would it increase it?

heh i just want to think that. I'm not actually thinking that.

Well if your going to double the car's hp, it definately will decrease the life of it. Basically everything is moving twice as fast as its made for.

driving your car hard decreases the engines lifespan...

Leaving your car parked in your garage for a couple years decreases its lifespan.

:werd: H4ly2nr, set it up properly and it will still run quite some time.

Not exactly, I think it would be under twice as much stress, but not going twice as fast.

Turbo'ing any engine will decrease the lifespan of it, however if you add a turbo to an engine that was built for it, it will still have a relatively long life.

everything will decrease the life of your car, enjoy it while you have it :thumbsup: :burnout:

you're right. the big problem with putting turbo's or superchargers is the stress it puts on the other engine parts. Basically, a turbo has the same effect as increasing your compression ratio... Increasing the compression ratio means more pressure in the cylinder which leads to prblems if your engine components can't handle the added pressure.

What? How can you "add" a turbo to an engine that was built for it? I'm assuming he's talking about the Celica GT-S that's in his profile. So his engine is not built for it to begin with, and turboing it definately will decrease the life of the engine. And relatively long life is subjective. How long is relatively long? Bottom line, turboing it will be more detrimental to the engine than not turboing it.

I'm sure some motors are built for a turbo and do not come with one. Not a celica though.

older celica's came with a turbo... the 4wd celica. that was a pretty good car.

^^the new celica's don't use that same engine.

The N/A Celica engine, the 3S-GE, in the 4th and 5th gen celicas, had a similar engine. There were many similarities, however a couple differences I can think of.

-3SGTE has piston oil squirters
-3SGE has higher compression ratio
-different intake manifolds
-different cams

my car has a static compression ratio of 8.1:1. That is meant for boost.

just think about it, when you get more horsepower what does that mean? A bigger more powerfull explosion, of course it will wear parts out quicker.

Anytime you exceed the engineers margins of safety, and push beyond what the stock parts were DESIGNED to handle, you will decrease the lifespan of your engine, that's just common sense.

Doesn't matter if it's NA, Turbo or Nitrous, stock will always last longer and be more reliable.

7.6:1 here, and my car will still probably blow a piston before yours, damn old school short commings :rofl:

7.6:1 seems incredibly low to me.
you must be running 40-50psi ... :rolleyes: :D

it's a spirit, he never said he was making crazy power.

and it is common sense that boosting your car will decrease engine life. you are adding stress that the motor was never designed to take, that isn't to say that it'll blow up within a few months, or even a few years, but it will not last as long as it would have before. another thing that you might want to keep in mind though is that if you don't turbo your car, you might just drive the piss out of it trying to prove to yourself that your car is fast, when it's not, therefore doing damage to in anyway. if you know in your heart that your car has the potential, you may not be as tempted to drive the piss out of it, therefore increasing engine life. (ya, right)

found out it was slightly higher but still sub 8:1, just a quick search on turbododge.com

there is a reason that stock high milage (100,000+km's)turbo dodge bottom ends will hold togeather at 25+psi on a t3 ;)

sorry mate, no intention of hurting your pride. I was just pointing out that you don't need to have a high compression ratio to make good power out of a turbo car if you provide even just a little bit of boost. at 7.6:1 you would really only need to make 14psi at sea level to bring the simulated compression ratio up to nearly 15:1. assuming of course that it is essentially doubling the ambient pressure therefore doubling the amount of air/fuel mix that passes into the cylinder, it's probly not quite this extreme, but that's not the point. if im way off base please correct me.

and i got a question for ACX, how do you have a JDM srt-4? i don't get it.


oh and so this isn't thought of as a stolen thread, ya, turboing your car is detrimental to its health.

i think he's joking with the jdm srt4 :thumbsup:

as for the dodge bottom end, its built like a brick house with really low compression, but has a non cross-fow 8v head designed some time in the 70's :(

the newer 2.4 is a better design,but costs much more then $180 for a motor that my 2.5 costs ;)

Well if u wanna turbo your engine, that means u will drive it harder, if u say u wont, then why are u turboing? And driving it harder will decrease engine life, It's quite simple!:burnout:
